HCDP Cationic Polyester Chips for High-Performance Blended Fibers

HCDP Cationic Polyester Chips for Staple and Filament Applications

The HCDP series contains over 10% cationic-modified monomers. In downstream applications, it is typically blended with bright polyester chips or recycled PET bottle chips in a 5:5 or 6:4 ratio, followed by drying, crystallization, melt spinning, and fiber setting to produce staple fibers or filaments.

 

Features

1. Can be blended with acrylic or wool and dyed in the same bath with cationic dyes.
2. Bright colors, fast dye uptake, and excellent color fastness.
3. Standard moisture regain of 1.5%, providing good wearability and comfort.

 

Application

Widely used in:

• Wool-like fabrics
• Acrylic alternative products
• Electrostatic flocking
• Printed blankets
• Suede fabrics.
